SPECIFICATION forming part of Letters Patent No. 232,813, dated October5, 1880. Application filed J illy 2, 1880. (No model.)

To all whom it may concern:

Be it known that I, HENRY GOEE, a citizen of the United States, residingat Corning, in the county of Steuben and State of New York, haveinvented a new and useful.improvement in indow-Blinds, of which thefollowing is a specification.

The invention relates to improvements in the manner of rolling the slatsof window-blinds, and is particularly adapted to the workin g of insideblinds constructed with glass slats.

The object of the improvement is to dispense with the cumbersome outsideconnections ordinarily used and the accompanying wire staples, whichweaken and render liable to fracture the slats, when made of glass,through the eX- pansion and contraction caused by changes oftemperature, and render more convenient the operation of rolling theslats.

The invention consists in forming the slats of wiudow-bfinds with atiXed wheel or pulley on one end, suitable in form for the reception ofa band or cord, and in passing a band or cord around each, andpreferably over sheaves at the top and bottom of the frame, bringing theends together and attaching them to a sliding bar or other suitabledevice, so that by a movement of the band the slats will all besimultaneously rolled, and, being equally balanced, will remain in anyposition in which they may be placed.

In the accompanying' drawings, in which similar letters ofreferenceindicate like parts, Figure l is a front elevation; Fig. 2, auedge view with one of the st-iles, F, of the frame removed, exposing theends of the slats G and Fig. 3

is an enlarged detail view of one of the grooved pulleys, showing thecord B and india-rubber band H in section.

The cord B is passed around each of the pulleys A and over thecarrier-pulleys G, the ends uniting at the sliding bar D, which slidesunder bands attached to the frame To the sliding bar D are aliiXed aneccentric, a, and a stud, b, between which the ends ot' the cord B arepassed, and are made fast by turning the eccentric a so as to press themfirmly against,

the stud b. Hence when the slide D is moved upward or downward itsmotion is transmitted through the cord B and pulleys A to the slats G.Though not indispensable, I make use oi' the carrier-pulleys C above andbelow the slats, to provide against the possible slipping of the cord onthe pulleys ot' the upper and lower slats by passing' the cord aroundtheir entire circumference, the same as the others. As a furthersafeguard against the slipping of the cord, (though I do not deem thisindispensable,) I make use of an elastic band ot' indiarubber, H, at thebottom of the groove ofthe pulleys.

ln a window-blind, the cord B, in combination with the pulleys A,india-rubber band H, carrier-pulleys C, sliding bar D, eccentric a, andstud b, all constructed, arranged, and operatin g substantially as setforth.
